Question

Is image scale the same as focal length?

Answer 1

Explanation:

In this case, a large CCD with a long-focal-length scope gives the same field as a small CCD on a short-focal-length scope, but the image scale is greater on the larger.

Answer 2

Answer:

no

Explanation:

The focal length of a lens determines the magnification at which it images distant objects. It is equal to the distance between the image plane and a pinhole that images distant objects the same size as the lens in question.
